How can I understand more harder while loop??

Question

for example take this c++ code:-
int x=0;
while(0){
if(x<3){
x++;
}
cout << (x=='1')

Answer 1

You can shorten that and make it execute by...
while (x < 3) {
x++;
cout << (x == 1);
}

Also what do you not understand about while loops?

Answer 2

the while loop in this example is not going to be run even one time

this while loop's condition is 0 which means false.

while(0) is equal to while(false)

when condition is false the loop do not run......

here loop will not run and it will go to
cout<<(x == '1')
which will print 0 because it is false that x=='1'

Answer 3

thanks Alex for supporting me.
and i don't care if anyone downvote me. 😂😎

Answer 4

Whoever downvoted @Raj Chhatrala:
He is right. The code in the body of a while(false) loop won't get executed.

Answer 5

I think he wanted to write while(!x)
